以上图片为搭建完毕的实验装置的局部图（各种管路盘根错节，看着头皮发麻）本次实验通过浓硫酸与硝酸钾生成硫酸氢钾与硝酸的反应，并将硝酸蒸馏出反应体系，以达到制备发烟硝酸的目的原料为K K鲨鱼（90%以上浓硫酸

在做“估算高锰酸跟离子大小”的试验时,取一颗体积为V的高锰酸钾小颗粒配置成10毫升溶液，从中取出1毫升溶液加入9毫升水稀释，溶液颜色变浅，从稀释后的溶液中取1毫升溶液加A入9毫升水稀释，溶液颜色变得更浅

一天闲来无事，望着之前买来就没用过的硒，就想着能不能用这个搞一些别人没搞过的东西，于是连想起之前弄的硫氰酸，就搜索了一番，发现硒氰酸钾可以用氰化钾与硒反应制，但由于本人没有，所以采用另一种方式:亚铁氰化钾与硒共熔制取冷却后加水溶解
